Freescale Semiconductor has introduced a range of fully programmable wireless charging ICs and reference designs targeting automotive and consumer applications. The new Wireless Power Consortium (WPC) Qi-certified transmit controller ICs and reference designs are fully qualified and available in market. Freescale’s programmable wireless charging solutions offer groundbreaking design flexibility, combining silicon and software to give systems designers advanced technology to help redefine mobility. The new offerings unleash design innovation and enable the rapid development of differentiated wireless charging systems. The flexibility in design is provided through a programming interface that places maximum control of the end-solution in the product developer’s hands.
Freescale is addressing the need of highly flexible solutions that allow for innovative, highly customizable implementations by providing differentiated wireless charging solutions to meet the needs of both automotive and consumer applications. Its customizable automotive solution consists of a Qi-certified transmit controller IC and accompanying reference design. The programming interface allows systems designers to address critical, auto-specific issues such as avoiding key fob and car radio interference. The entry-level device, MWCT1001A, provides a comprehensive and cost-effective multi-coil wireless charging transmit solution, while MWCT1003A is the premium option providing more feature-rich capabilities. Integrating technologies such as Near Field Communication (NFC), multi-standard support, or CAN technology is easy using MWCT1003A, and is showcased on the reference design - WCT-5WTXAUTO. The auto-focused ICs meet AEC-Q100 requirements and support any 5W coil topology.
For consumer applications, Freescale offers the MWCT1000 Qi-certified transmit controller IC and the associated WCT-5W1COILTX reference design, addressing 5W single-coil applications. This turnkey solution dramatically reduces time-to-market, provides exceptional performance and low bill-of-materials cost, while maintaining the principle of design flexibility. For even greater design freedom and feature integration, Freescale offers the MWCT1101 controller IC, opening a new range of possibilities for product innovation.
